Running the simulation

Simulations in three-dimensions are performed in an analogous fashion to those in two dimensions. In this example, a focused velocity source from a rectangular piston is incident on a layered medium. The sensor mask is defined as a set of cuboid corners that covers the central x-y plane.

To allow visualisation of the source elements within the grid, the source mask is assigned to the optional input parameter 'DisplayMask'. This mask is overlaid onto the plot during the simulation. The optional input 'DataCast' is set to 'single' to reduce the computation time, and the 'PlotScale' input is used to define suitable plot limits for the display of the normal and shear stress.
